The application of X-ray powder diffraction to the analysis of dust contaminants collected on membrane fibers is discussed. The advantages and disadvantages of the internal and the substrate, or external, standard procedure are also considered. The latter method, currently in use at NIOSH, is described in detail, emphasizing the use of silver membrane filter for redeposition of the dust sample and for the correction of matrix absorption. The analytical procedure has been applied to the analysis of free silica (7631869), zinc-oxide (1314132), zirconium-oxide (1314234), and chrysotile (12001295). X-ray powder diffraction has assumed increasing importance as an analytical technique for the identification and quantification of contaminants in the workplace environment. The authors conclude that, although the major use of this technique has been for the analysis of free silica, talc, and asbestos, the increasing need for the quantitation of chemical compounds as opposed to chemical elements has made the X-ray powder diffraction technique increasingly important to industry.
